I store it in postgresql (http://www.postgresql.org), which is an excellent database management system. PHP is a scripting language that delivers HTML information to your browser. Then PHP should query postgresql for listing information and then delivers it to your browser for you to see the website. If PHP didn't have to query any database, it will be extremely fast. Querying the database is the slow part, and is the part that requires most engineering effort in order to make pages appear fast. In regards to real estate, I'm in real estate because I like real estate :) ! It's exactly the same as I like developing website & research.... I enjoy doing real estate transactions, that's why people benefit when buying with me. You’ve got to store the information some where.

I can't imagine anybody thinking it is slow. Probably 5 times faster than any other site I have seen. And why are you a realtor again? I don't even get all that database stuff. You say "design your database" but then you say "adding a database" slows it down. So if you have no database...? Impressive. I can’t imagine anybody thinking it is slow.

It's good that you think its fast, even after I downgraded the machine. The old machine had a dual core Opteron on 1GB RAM. I actually found that I get a very reasonable performance on a Sempron 64 bit also on 1GB of RAM, I just had to correctly schedule priorities ! board & processor $75, ram $41 and I had an old case. I use GNU/Linux (ubuntu), apache, postgres & php and edit using emacs. Its all about how you design your database, creating the correct indexes and using the powerful features in your tools. PHP is very fast. Adding a database whether it is mysql or postgres, will slow it down. It then becomes your job to optimize queries so that scripts run faster. There's no magic or secrets about it.

How do you make it so fast? How many homes are in your database?
How do you make it so fast?

Mainly when trying to download updates for attached peripherals. The problems were easily corrected by unhooking the KVM switch. Regards, LaMont M,
